Predicted to be involved in tRNA-type intron splice site recognition and cleavage. Predicted to be part of tRNA-intron endonuclease complex. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 2A; pontocerebellar hypoplasia type 4; and pontocerebellar hypoplasia type 5. Orthologous to human TSEN54 (tRNA splicing endonuclease subunit 54). [provided by Alliance of Genome Resources, Apr 2022]
